Turntable with robotic arms draws beautiful spirographs

Artist Ally Mobbs has built a turntable that can draw. Mobbs attached robotic arms equipped with pens to a turntable, then allowed the rotations of the record players to create geometric shapes made out of curves. Adjust the settings of the turntable, and the drawing changes. The piece debuted in Montreal, where hip hop collective Beat Picnic played the turntable.
